T O NY BUDZINSKI, OF VIRGINIA, MINNESOTA To all whomit may concern: i

Bc it known that I, TONY RUnzINsKI, a citizen ofPoland, residing at Virginia, in the county of St. Louis and State of Minnesota, have inventedcertain new and useful Improvements in Spark-Arrcsters, of which the following is aspecification.

This invention relates to certain new and useful improvements in spark arresters and has particular reference to'a spark arrester especially designed for association withthe smoke stack of a railroad steam engine, although the device may be applied to a chiInmay: associated with any type of furnace.

he primary object of theinvention resides in the provisionof guiding ribs or vanes disposed within the outlet end of a chimney with a hood detachablymounted on the chimney and having a central opening disposed above the" chimney outlet with the sparks and cinders escaping from the ChlIIlney directed into engagement with the hood for arresting the same and causing a precipitation in proximity to the outer wall of the chimney.

With the above general objects in view and others that will appear as the nature of the invention is better understood, the invention consists in the novel form, combination and arrangement of parts hereinafter more fully described in connection with the accompanying drawing and in which like reference characters indicate corresponding parts throughout the several Views.

In the drawings,

Figure 1 is a side elevational view of the upper end of a chimney with the spark arrester attached thereto,

Fig. 2 is a top plan view of the same, Fig. 3 is a vertical sectional view taken on line IIL-III of Fig. 1 showing the curved vanes upon the inner face of the chimney, and

Fig. 4 is a cross sectional view taken on line IV-IV of Fig. 1 showing the side openings in the chimney hood and the spark ar resting vanes for directing the sparks and cinders outwardly of the chimney adjacent the walls thereof.

Referring more in detail to the accompanying drawing, there is illustrated a spark arrester designed for attachment to smoke stacks or chimneys of any character, the present invention belng pre erably designed as a spark arrester forthe smoke stacks of steam engines, the reference numeral 1 designates a chimney open at its upper end and having Specification of Lett ers l atent.

spark and cinder directing vanes secured to theinner walls thereof.

These vanes are in the form of angle plates shown in Fig. 3'while the upper edgethereof terminates ata point spaced from the vertical central axis of the chimney as clearly 4. Any number of the chimney 1, four being shown as equidistantly spaced within the chimney.

hood is mounted on the open upper drical wall 5 open at its lower end and of a size to provide an annular chamber. surrounding the chimney, with angle brackets 6 carried by the inner'face of the lower end for detachable mounting inbrackets 7 secured to the outer face of the chimney 1. The upper end of the hood 5 is provided with a central opening 8 and is spun inwardly to.

form an arched abutment wall 9 for the sparks andcinders, the edge of the wall 9 surrounding the opening 8 extending over the open upper end of the chimney 1. The side wall 5 of the hood is provided with cut away portions 10 to permit the lateral escape of sparks and cinders that are retarded in their escape by the hood.

In the operation of the device, smoke and gases escaping from the chimney 1 will pass upwardly through the central opening 8 in the hood and will not in any manner interfere with the draft of the furnace. By the particular arrangement and design of the vanes l, sparks and cinders passing up- 1 and embodies a cylin- V is easily "tion and arrangement of parts herein described and claimed. 1

What is claimed as new is:

1. In a device of the class described, a chimney a spark arrester associated with the chimneyand secured to the inner face thereof, the arrester being constructed to provide an unobstructed vertical axis and vertical radial passages in the chimney, said spark arrester including a plurality of vanes, each embodying a curved base flange secured to the-inner face of the chimney and arranged at an angle to the vertical axis of the chimney, each vane confined within an arc of less than ninety degrees, and all of the vanes equidistant-1y spaced, a vane wall extending aterightangles'from the base flange with the'free edgelying in a" plane parallel with the -vertical axis ofthe chimney and the lower end of the vane wallmerging into the base flange. V i

2. Ina device of the class described, a

chimney, aspark arrester associated with the chimney and secured to the inner face thereof, the arrester being constructed to provide an unobstructed vertical axis and vertical radial passages in the chimney, said spark arrester including a plurality of vanes, each embodying a curved base flange secured to the inner face of the chimney and arranged at an angle to the vertical axis of the chimney, each vane confined within an arc of less than ninety degrees, and all of the vanes equidistantly spaced, a vane wall extending at right angles from the base flange with the free edge lying in a plane parallel with the vertical axis of the chin ney and the lower end of the vane Wall merging into the base flange, and a hood removably supported on said chimney and having an arched upper wall provided with .a central opening overlying said chimney,

the edge wall of the opening being spaced inwardly of the upper edge wall of the chimney.

In testimony whereof I afiix my signature in presence of two witnesses.

TONY RUDZINSKI.
